SeparationRayShape2D
====================

**Inherits:** :ref:`Shape2D<class_Shape2D>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A 2D ray shape used for physics collision that tries to separate itself from any collider.

.. rst-class:: classref-introduction-group

Description
-----------

A 2D ray shape, intended for use in physics. Usually used to provide a shape for a :ref:`CollisionShape2D<class_CollisionShape2D>`. When a **SeparationRayShape2D** collides with an object, it tries to separate itself from it by moving its endpoint to the collision point. For example, a **SeparationRayShape2D** next to a character can allow it to instantly move up when touching stairs.

:ref:`float<class_float>` **length** = ``20.0`` :ref:`🔗<class_SeparationRayShape2D_property_length>`

.. rst-class:: classref-property-setget

.. _class_SeparationRayShape2D_property_slide_on_slope:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **slide_on_slope** = ``false`` :ref:`🔗<class_SeparationRayShape2D_property_slide_on_slope>`

.. rst-class:: classref-property-setget

- |void| **set_slide_on_slope**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **get_slide_on_slope**\ (\ )

If ``false`` (default), the shape always separates and returns a normal along its own direction.

If ``true``, the shape can return the correct normal and separate in any direction, allowing sliding motion on slopes.
